Problems solved by technology
[0005] The invention overcomes the deficiencies of the prior art. In order to solve the problem that when the traditional vacuum suction cup adsorbs and clamps the workpiece, the mixed liquid such as cooling liquid enters the vacuum chamber, which affects the surface quality and quick disassembly of the workpiece when the workpiece is disassembled. The invention provides a mechanical The air-water separation structure design of the vacuum chuck used for processing and clamping, through this design, the vacuum air flow channel of the suction cup is isolated from the cooling liquid channel, and the mixed liquid such as cooling liquid is prevented from entering the vacuum chamber

The invention discloses an air-water separating structure of a vacuum sucker for machining clamping. The air-water separating structure mainly comprises air vents, a water-insulation cavity and an anti-seepage ring, wherein the air vents are formed in the water-insulation cavity; the air vents and the water-insulation cavity form an air channel; the air vents, a vacuum cavity of the sucker and a sealing surface of the sucker are combined to form a vacuum air channel; and the anti-seepage ring is positioned at a sucking end of the sucker and is spaced from the vacuum cavity of the sucker to form a water-insulation surface. The air vents, the water-insulation cavity, the anti-seepage ring and a splash-proof ring are skillfully and simply designed, so that the air-water separating structure of the vacuum sucker is formed, the problem that mixed liquid such as cooling liquid permeates into the sealing surface and the vacuum cavity during processing is solved thoroughly, a workpiece can be detached directly, quickly and easily in the direction perpendicular to the sealing surface of the sucker, and the problem that the surface quality and rapid detaching of the workpiece are affected by a residual adsorption force of a liquid film and liquid volatilization residual accumulated matters which are caused by permeation of the cooling liquid during detaching is solved.
Description
technical field [0001] The invention relates to the technical field of machining, in particular to an air-water separation structure of a vacuum suction cup for machining and clamping. Background technique [0002] In the field of mechanical processing, it is a common clamping method to use vacuum suction cups to adsorb and clamp workpieces. The design and use of vacuum suction cups usually focus on three points: the effective vacuum chamber projected area, the surface of the suction cup and the workpiece clamping adsorption positioning surface Fitting precision, vacuum sealing performance, the core of the concern is the workpiece deformation and vacuum tightness (vacuum degree) of vacuum adsorption, but in the state of machining using coolant, the seal between the suction cup and the workpiece cannot reach 100%, there is no The system considers the influence of suction cup clamping on the appearance quality of the workpiece positioning surface and quick disassembly when dis...
